I have connecting problem.

My setting...

1. OS : win10 x64

    emulator : J-link(EDU)

2. installed

    1) nRF5x-Command-Line-Tools_9_7_3_Installer.exe

    2) nrfgostudio_win-64_1.21.2_installer.msi

    3) J-Link driver(6.32d) , I already tried 6.22g.

3. Test board : "nRF52832 Bluefruit feather"

    link : https://cdn-learn.adafruit.com/downloads/pdf/bluefruit-nrf52-feather-learning-guide.pdf

4. J-Link command message

5. My cortex-M3 board connected to same J-link(SWD), but nrf52382 not connect.

6. Also, my other laptop same.

Please advise. Thanks!

    Hi, Håkon

    I find  cause of my problem.

    (A yellow signal is "SWDIO" and blue signal is "SWCLK")

    A red rectangle in this pictre is ACK signal ( nRF52 -> J-link).

    The voltage level of this ACK signal  is 3.3V ~2.5V.

    Thus, this signal is all "High vlotage".

    I am checking and thinking to solve this problem.

    Now I focus on "Pull-up registance".

    (I am aware that nrf 52 has internal pull-up registance.)

    Thanks!!

    Hi,

     

    Sorry for the late reply. I checked internally, and this is not something that we have seen before.

    The SWDIO pin is bidirectional, meaning it can be both input and output seen from both the debugger and the nRF.

    It looks like the the debugger overrides the output from the nRF, thus you only get a small "ripple" with the response from the nRF. Does this happen often in the trace? Normally, the segger connect procedure does several re-tries if it fails to connect.

     

    Best regards,

    Håkon
